Hi @Marwan Samrout , Thaks for reaching out. To verify the access token received from the client-side in your Node.js server, you can use the passport-azure-ad library. This library provides a middleware that can be used to authenticate the incoming requests based on the access token.

Hope this will help.
Thanks,

Shweta
